Kuma’s Corner in Chicago specializes in hamburgers—big, juicy burgers. They really like their punk and heavy metal and frequently name their burgers after their favorite bands. They have a wicked sense of humor, too—on their Facebook banner image they call themselves “Purveyors of the Bovine Genocide.” I’m not super familiar with Chicago—but I really like the Kuma’s attitude, and I really hope they are (or are rapidly on their way to becoming) a beloved Chicago institution.

They have two locations, Kuma’s Corner on 2900 Belmont and Kuma’s Too on 666 W. Diversey Parkway. Every month each location introduces a new themed burger that’s only available for that month and only available at that location.

This month, the Belmont location’s themed burger, which pays homage to the heavy metal band Ghost from Linköping, Sweden, is a doozy. The thing about Ghost is that they’re not just any heavy metal band: They’re a bit like the Residents in that they haven’t disclosed their true identities and they’re really theatrical. The five instrumentalists all wear identical black robes on stage, and the lead singer, who goes by the name Papa Emeritus II, wears skull make-up and the garb of a Catholic Cardinal.

Here are the ingredients of the Ghost Burger, according to a Facebook blast they sent out when October arrived:

In the spirit of our undying reverence for the lord and all things holy, we give you the Ghost which we think is a fitting tribute to the supreme blasphemous activities carried out by the band itself.
10oz patty
Ghost chile aioli
Slow braised Goat shoulder
Aged white cheddar cheese
Red Wine Reduction (the blood of christ)
with Communion Wafer garnish (the body of christ)
